DIAGNOSIS. An apterous black species defined chiefly by the distinctive aedeagus, the elytra short, EL/EW 1.64, and apically truncate in male, with pubescence arranged in a single row on each side of elytral ridge while being slightly sparser in odd than in even intervals. A similar species, G. wrasei , from the adjacent region, Yunnan, China, has the head, the genae, the pronotum and the elytra shorter, and the internal sac of the aedeagus with both dorsomedial and left lateral sclerites more in number, eight and six, respectively.

DESCRIPTION. BL 22.7 mm. Body ( Fig. 8 View Figs 7–9 ) black and rather shiny. Meshed microsculpture superficial, isodiametric on head and along sides of pronotum, slightly to moderately transverse in front of neck constriction and along sides of basal 1/2 head, almost obliterate before.

Head with frontal carina nearly smooth and glabrous, well traceable up to the level of eye mid-length, coarsely and moderately densely punctate in basal half, including within a very shallow impression on vertex.

Pronotum broadest almost two fifths from apex, with sides slightly sinuate in basal half and very slightly converging basad. Base truncate, with angles right and blunt. Apex slightly sinuate and straight at middle; angles slightly rounded and a little projecting. Disc moderately convex, moderately and very densely punctate at middle, somewhat rugose-punctate toward lateral margins and apically. Median line fine, very gently impressed, obliterate in basal fifth and in apical sixth. Basolateral foveae in form of finely impressed lines traceable in basal half and as fine sublateral lines extended apicad; lateral margins explanate outside these foveae and less so outside sublateral lines. Lateral bead fine, indistinct at base and at apex. Basal transverse impression fine yet distinct, angulate apically.

Elytral apices truncate combined, sutural angles right, outer angles widely rounded. Pubescence by comparison moderately dense, arranged in a doubled row on each side of interval 4 in basal third and in 2–3 rows on the outside of ridge 8. Interval 3 with three discal setae.

Aedeagus ( Figs 59 View Figs 44–65 , 96–98 View Figs 96–101 ): left paramere subtriangular, with dorsal margin rounded, ventral margin straight and apex slightly pointed. Internal sac simple, with no laterobasal bulbs, six dorsomedial and two left lateral sclerites — the absence of the left laterobasal bulb may have evolved from that being enlarged first and merged into the sac’s body after.

DISTRIBUTION. Known from the type locality only.

NAME. Refers to the apically truncate elytra.

HABITATS AND HABITS. The only specimen was hand collected under a tree trunk on the ground in a cloudy forest.
